Maritime kits are prepared according to current Maritime NZ rules and must be signed off by the skipper of the vessel in person. (We cannot ship this kit out - must be picked up instore and signed off by the skipper). The kit comes with certification for 12-months and all products will have sufficient expiry to last that time period. This is for a complete kit but top ups can be done annually as well. To arrange a refill, email Andrea or phone on 068357948.
